I'm mainly a lead guitarist who originally used .10 - .52 in C# but I couldn't stand how much thicker the bottom three strings were than the top three. I went and bought .11 - .49 and haven't put them on yet. Will it slow down my playing? Should I return it and go for .10s?
No string guage shouldnt slow your playing unless the action gets really stupidly high. I recommend 13s for C or C# though, gives you great tension and tone
If anything the lighter strings will make playing a little easier, as there's less tension.

I say stick with the 11s, you could do 10s if you want the strings to be really loose.

I'm just going to return them and get a thinner gauge.
I like loose strings a lot better.
